Answer:

255

Step-by-step explanation:

We need to find 75% of 340...

75%*340

Let's convert 75% to a fraction to make the math easier...

75/100*340

Now let's simplify 75/100 to again make it easier...

3/4*340=255

The endpoints of GH are G(3,3) and H(-7,7). Find the coordinates of the midpoint M.

sesenic [268]

Step-by-step explanation:

Hey there!!

You can simply use midpoint formulae to find midpoint of the coordinates.

Here, Given that;

G(3,3) and H(-7,7).

Using midpoint formulae,

$midpoint \: of \: gh = (\frac{x1 + x2}{2} ,\frac{y1 + y2}{2}$ )

$midpoint \: of \: gh = (\frac{3 - 7}{2} ,\frac{3 + 7}{2}$ )

After simplifying it we get,

= (-2,5).

Therefore, midpoint of GH is M(-2,5).

Hope it helps....

What is GE ? Enter your answer in the box.

Flura [38]

The length of GE is 10 units

Explanation:

Given that the length of XY = 5 units and YZ = 4.6 units

The length of GE:

We need to determine the length of GE

From the figure, we can see that ZY bisects GE and XY bisects EF.

The lines ZY and XY both bisect GF.

The midpoint theorem states that "the line segment connecting the midpoints of two sides of a triangle is parallel to the third side and is congruent to one half of the third side".

Since, we have,

EX = XF and X is the midpoint of EF

GY = YF and Y is the midpoint of GF

Since, XY is the line segment that connects the midpoints of the two sides of the triangle.

Applying the midpoint theorem, we have,

$GE = 2XY$

$GE = 2(5)=10 \ units$

Thus, the length of GE is 10 units.

Answers for the 2 boxes please:)

Answer:

(5,-5)

Step-by-step explanation:

Eliminate y-term

$(2x + 5x) + ( - 3y + 3y) = 25 + 10 \\ 7x = 35 \\ x = \frac{35}{7} \\ x = 5$

We can eliminate x-term but for this system of equations, eliminating y-term is faster.

Substitute x = 5 in any given equations.

I will choose to substitute in the first equation.

$2x - 3y = 25 \\ 2(5) - 3y = 25 \\ 10 - 3y = 25 \\ 10 - 25 = 3y \\ - 1 5 = 3y \\ 3y = - 15 \\ y = - 5$

Answer Check

Substitute both x-value and y-value in any given equations

$2x - 3y = 25 \\ 2(5) - 3( - 5) = 25 \\ 10 + 15 = 25 \\ 25 = 25$

The equation is true. (It is better to check both the answer for both equation.)

Thus the answer is (5,-5)

After being discounted 40%, a weather radio sells for $35.97. find the original price. (round your answer to the nearest cent.)

tia_tia [17]

It is given in the question that

After being discounted 40%, a weather radio sells for $35.97.

It means the weather radio sells at a 60% of original price.

Let the original price be $x.

Therefore according to the question,

$60% \ of \ x = 35.97
\\
0.6x = 35.97
\\
x = $59.95$

Therefore the original price of the weather radio is $59.95.

LIMITED TIME PLS HELP: Four, two-person tennis teams played tennis matches. Ivan collected the number of points won by both play

Marina86 [1]

For this, you just need to add up the team points together. Also remember that the problem says "60 pts or less", not "less than 60 pts". This means teams with 60 pts will count for the question.

Team 1: $38+22=60$

Team 2: $42+18=60$

Team 3: $21+42=63$

Team 4: $25+40=65$

From the math above, we can conclude that 2 teams had won 60 or less.
